Hello guys, so I have a question. I have water loss with my omi. I say about 1500km/1L water. Last year I had the head seal done. They were also re-planned. Krummer gasket/water pump/dental belts were also changed. Now I wanted to drive in 2 weeks on holiday and was at a workshop today to find out why the car loses water again. The mechanic wanted to check if he can measure exhaust gases in the water tank. He then pushed a small pump on top of the part and sucked in the air. Until then everything was fine. But without being able to measure it accurately, the water rose up in the container and started to bubbling. He said that it should not overflow like this and at the same time throw air bubbles. The mechanic said that it could lie on the ZKD or on the water pump. nte. Has anyone ever had such a thing? Can it be that after a year the ZKD is flat again?? I really spin on the bike. I think I can give the holiday now. Hope for some useful tips from you. Greetings Aki
